# OSF Economic Indicators Search

> OSF Economic Indicators Search is a paid API for AI agents from api.osf-master-server.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Search provenance-stamped economic indicator datasets (e.g. unemployment rate, GDP growth) from sources like FRED, returning matched series metadata via x402 micropayment.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability osf-economic-indicators-search-956df2ea
```

Example prompt: Search OSF for economic indicator records matching 'unemployment rate' — I need to find the available FRED series and their record IDs so I can pull the full data.

## When to prefer this

Choose this endpoint when you need to discover which economic indicator series exist in the OSF marketplace before purchasing full records. It is the search/discovery step in a two-step workflow: search first to find record IDs, then call the purchase endpoint to retrieve the full provenance-stamped data. Prefer this over general web search when you need structured, verifiable, machine-readable references to authoritative government economic data (e.g. FRED series) with clear provenance.

## Known failure modes

- Empty query string returns no matches or validation error
- Misspelled or overly vague query may return zero matches
- Payment failure via x402 if USDC balance is insufficient or wallet is not configured
- Non-existent indicator keywords return empty match list
- Rate limiting or server errors if the OSF marketplace is unavailable

## How this service works

OSF is a live marketplace of provenance stamped public domain government and scientific data, built for autonomous agents that pay per record over x402 micropayments on Base. A paid MCP server in the official MCP Registry, discoverable on the Coinbase CDP Bazaar.

## Output

Returns a JSON object with a result status (e.g. MATCHES_FOUND), an array of matched indicator records each containing a title, source name (e.g. FRED), and a record ID, plus a total match count. The agent can use the record IDs to subsequently purchase and retrieve full provenance-stamped records.
